Abstract: CuInS2 nanocrystals doped sodium borosilicate glass were prepared by employing both sol-gel and atmosphere control methods. Morphology and microstructure of CuInS2 nanocrystals in the glass were characte-rized by means of X-ray powder diffraction(XRD) and transmission electron microscope(TEM). Femtosecond Z-scan technique was employed to study the third-order nonlinear optical properties of the glass. The results show that CuInS2 nanocrystals in tetragonal crystal system form uniformly in the glass, and the size of the nanocrystals is about 10 nm. The results of femtosecond Z-scan technique show that the glass exhibits excellent third-order nonlinear optical properties, and the third-order nonlinear optical refractive index γ, absorption coefficient β and susceptibility χ(3) of the glass are determined to be 8.57×10-16 m2/W, 3.74×10-8 m/W, and 1.95×10-17 m2/V2, respectively.
